was only associated with large ocean racing and traditional sailboats The rapidly growing trend towards wheel steering has changed to include cruising and racing sailboats as small as 18 feet Many people once believed the only way toget theUfeelof a sailboat was with a tillerThe popularity of wheel steering as well as its practicality has shown even the most adamant tiller man that better feel and better boat control can be obtained with wheel steering Without the tiller sweeping theentire cockpit the crew can perform more functionally guests can relax more comfortably and shorthanded family sailing suddenly becomes simple Planning a steering system for a tiller conversion or an option on a new boat is not a casual matter and should be done with the utmost thought and consideration More time should go into the planning of acockpit than any other part of the boat this is where the crew spends the vast majority of their time whether the boat is for cruising or racing Moreover the cockpit is the base for handling sails as well as steering Thus in this one area of the boat comfort convenience performance and safety are all equally vital factors neglect even one and the pleasure of sailing is in ieooardvA major part of planning agood steering installation islocating thesteerer This must take location of the rudderpost winches main sheet and engine controls All must be located properly or moved to the appropriate location for a functional and comfortable cockpit The aft cockpit steering location is normally associated with h t e older traditional design where a worm gear type steerer to a rudderpost located in the aft end of the cock O p i t It is also the location used for the New Edson Rack and Pinion Steerer installed abovedeck directly toarudderpost located in thevery aft end of the cockpit or with atransom hung rudder The is often locatedwell aft in thecockpit in cruising and racing boats minimum distance 21 inches from the pedestal centerline to the aft cockpit bulkhead Theadvantageof any of theseaft steering installations is that the helmsman is well aft out of theway of crew members working winches From this position the helmsman sees all the action can cast off sheets or tail winches participate in cockpit conversation and has a complete view of the sails and rig In the midcockpit installation the helm is farther forward where the boat is wider so the helmsman can get more outboard instruments mounted in the cabin bulkhead can beeasily read the winches and cleats are more accessible to the helmsman whether they are forward or aft of the helm On a cruising boat this location clears the aft end of thecockpit forcrew members or guests not needed for handling sheets Neither the backstay nor main sheet need interfere with the helmsman standing behind the wheel and the helmsman has sufficient room to brace his feet without restriction With the helm in midcockpit winch location does become critical especially when installing wheel steer in in an exist in c o c k iwhere t winch locations are fixed concentrating both winches and helm in the middle of the cockpit can be most inconvenient for both helmsman and crew The forward cockpit installation places the helmsman close to the companionway under the protection of a dodger out of the way of winches and main sheet and in a wide part of the boat where head sails can be easily viewed fihoing the type of steerer is specifically covered on its I ppropriatepage of this catalog however each has certain which are best suited for a particular type boat Rack and Pinion Steering is most useful on boats from 16 to 40 feet where space under the cockpit floor is limited or for those small sailboats with transom hung rudders such as the trailerable models The inboard

plugged into these setups with a minimumamount of installation effort with the exception of building a cover over the steerer to serve as a helm seat Worm Gear Steering is often referred to as NonReversing meaning the feedback from the rudder will not normally turn the wheel when the helmsman lets go of the wheel These steerers are most often used on traditional boats with aft raked inboard rudders Because of the rake it is often impossible t o install a quadrant underthe cockpit floor This type of steerer is attached directly to the rudderpost above the cockpit floor at right angles to the rudderpost The steerer shaft may be fitted with a universal and an extra bearing to build in the exact wheel helm A wheel box must be built overthe steerer to serve as a helm seat This box can be kept as narrow as possibleso the helmsman can sit behindoralong side the wheel The box can have a flip up top to serve as a seat back for long watches at the wheel Engine controls can be located right on the sideof the helm seat within easy reach of the helmsman Despite the worm gear steerer being nonreversing there are always those boats with an excetional weather helm or oarticularlv hard steering For these boats we now offera fridtion shaft brak for all sizes of worm steerers Bulkhead Steerers are most advantageous for power boats motorsailers two station steering MidShip Cockpit boats and bridge deck console type steering stations generally found on custom racing boats Bulkhead steerers can be purchased for very small boats using direct sprocket and chain drive as well as 2l and 3l geared reduction sprocket and chain steerers for very large commercial vessels such as fishing boats and tug boats Pedestal Steering is well suited for both midship cockpit and aft cockpit boats with inboard rudders as well as transom hung rudders This system requires space under the cockpit floor for mounting sheaves sheave bracket or Radial drive Steering System It offers maximum flexibility in that any number of sheaves may be mounted to route wire rope around engine spaces through aft cabins or around fuel tanks etcThe pedestal type system comprised of sprocket chain and wire rope can be used very efficiently for both cruising and racing boats up to 80 feet by varying the size of the steering wheel and the size of the quadrant toeffectively changethe poweroutput necessaryto sail your boat This steerer is very popular and most versatile when planning your cockpit for convenience accessories such as brake guard tables instrument housings engine controls helm seat and autopilot drives PullPull Steering is a new system offered by Edson as an alternative to a sheave and wire rope system This System can be used with either Bulkhead or Pedestal Steerers with inboard or outboard rudder boats It is most advantageous for MidShip Cockpit and Aft Cabin boats when routing the steering cables from the Center Cockpit to the rudderpost can become complicated The PullPull System uses standard Edson components in conjunction with flexible conduit housing 7 x 19 stainless steel wire rope Unlike pushpull cables such as those used on engine controls pullpull is always in tension The result is very positive steering control without the play and lost motion generally associated with a PushPull Cable Each steering section of the catalog shows a chart for selecting the recommended size steering system for your boat Each chart is composed of information gathered from our many years of leadership in marine steering Due to the many variations in yacht

dummy rudderpost is going to be bolted to Bear in mind that this surface must be of sufficient strength as it must absorb all of the steering loads This platform must be 90 to the rudder on a plane where you wish to install the rudder lever Also note that the geared rack and pinion quadrant requires a minimum of 10 on each side of the dummy rudderpost to swing in This dimension will help in establishing the C dimensions Temporarily mount the dummy rudderpost and assemble the rack and pinion gear and housing Assemble the clevis the connecting rod and the rudder lever unit With C clamps attach the rudder lever unit to the rudder Now operate the steerer noting the rudder travel from side to side The location of the lever on the rudder either fore or aft or possibly even shimmed to starboard determines equal travel from side to side Take time with the positioning of this lever and be precise When you are satisfied secure all parts and install stops such as wooden blocks on each side of steerer to limit its travel to the desired arc Provisions for an emergency tiller should now be made if you do not already have oneCABLE SYSTEM FOR DOUBLE ENDERThe New Fig 345 Aft Mount Rack

sketch showing all dimensions in the drawing See Price SheetAType IIFIG 675 BRONZE SHAFT COUPLINGS Especially handy for connecting in line shafts of the same diameter Also used with rudderpost extenders on Worm Steerers and Rack and Pinion installations where the existing rudderpost is too lowt z lfor all available sizes see p r i s pagesWorm steerer installations must be well designed and well thought out from all standpoints The basic system is mounted at 90 to the rudderpost and is rigid at this point The SelfAligning Bearing supplied with the gear must be well bolted down to a timber or strong moldment on a fiberglass design It is important to design in the basic features that make for a successful installation It is recommended that the top of the wheel the actual part you hold onto be 31 79cm to 33182cm up from the cockpit floor This will allow standing beside the wheel without reaching down to the wheel also sitting in back of the wheel or alongside it and have the wheel at a convenient height Essentially a Worm Steerer is a nonreversing system with little to no feel and is most commonly used on a longkeeled cruising design The steerer design features more turns pf the wheel from hard over to hard over than is normally designed into a wire type of pedestal systems The Worm Steerers would then not be recommended for a shortkeeled fast turning boat or one that does not track as well as the longkeeled boats The nonreversing feature will hold the wheel in place on most boats most of the time It will give or turn if the boat is hit by a large wave or the boat has an excessive helm due to basic design force of the wind or balance of the sails The gears are strong and relatively heavy as they must stand all of the strain of the rudder when transmitted to the gear The shaft extension or the wheel shaft itself can be easily 9pated to an AutoPilot by the addition of the necessary Jilot sprocket The choice of the location is one that will allow the sprocket chain to be led at right angles to the worm shaft directly to the AutoPilot motor box When ordering advise Edson of Rudderpost bore diameter Keyway size and Keyway position these will be machined by Edson If a special A length is required be sure to include itFIG 390 Edson Meteor Steerer With Worm Fore and Aft of Rudderpost Wt 128 lbs1585 k A 311FIG 380 Edson Robinson Worm Aft Steerer Wt 128

shaft and an exfra SelfAligning Bearing for the needed forward wheel shaft support This combination can reducethe wheel angle by a maximum of 30 up or down That is if the rudderpost is at 45 to the waterline the wheel can be angled at only 15 Edson feels the maximum angleof the wheel should be no more than 20 Likewise on near vertical rudderposts the same setup can be used to give the wheel some aft rake This angle is important as it will give the helmsman room for his knees while the top of the wheel is closer to his arms If in doubt as to steerer size or if the boat is very heavygo larger Do Not compromise the final size For those boats where the rudderpost ends at the cockpit floor level Edson can furnish the Fig 675 Coupling and aFig 782 Rudderpost Extender of the correct size and

specifically designed for maximum performance and Edson reliability as well as ease of installation Each system is predrilledto accept any of the convenient addon accessories at any time Carefully review each type shown in the following pages as well as the Edson dataSheet for your particular boat Edson has over 1200 installation drawings which we call SDataSheets If you own a stock boat feel free to request a DataSheet on that boat or if you are building or purchasing acustom boat send us in aconstruction drawing or good sketch and we will gladly send a complete proposal and DataSheet representing a similar SYSTEMStypical installation may vary in wheel size sheave size chain d l e n g t h and quadrant size depending on the size and displacement of the boat and the type of sailing being done For cruising and offshore work a larger quadrant with more power output and more turns of the wheel hard over to hard over is preferable For racing a smaller quadrant with fewer number of turns and a larger wheel will provide faster action especially useful for downwind sailing For THE PEDSTAL STEERING SYSTEMd s s a nsizes see the table below Edson will also supply upon request Data Sheets and specific covering the best system for your boat For boats being able to use more than one system will be given in order of preference For specific information for converting or planning

t is best used where the rudder post has considerable rake forward or aft or where tanks cockpit drains exhaust lines or other obstuctions require routing of the wire rope through two or more sheaves This uses wood supports to tie the cockpit to the hull keeping steering loads from wracking the cockpit This system has been used for many years and is excellent for conversion of tiller boats as well as new installations Sheave Bracket System is ideal for installation on stock boats as well as by owners or yards It is excellent for those boats having the cockpit seat risers along side the radius of the quadrant where wooden blocks can be glassed in on the sail locker side of the seat risers flush with the bottom of the cockpit floor This unit has a built in quadrant stop and fully adjustable sheaves Radial Drive Steering System is ideal for sail or power boats up to 40 feet with vertical or nearly vertical aluminum or stainless steel rudderposts whe7e cables can be led directly onto the drive wheel The Radial Drive can also be used on boats larger than 40 when using an independent rudderpost stop On boats over 40 feet Edson would like complete blueprints and requires the final approval of your naval architect This system is designed to be simple and economical with fewer moving parts Feel and performance is equal to other Edson steerers It can be used equally as well with pedestal or bylkhead steerers on any boat with adequate clearance around the rudderpost It can also be used in conjunction with the PullPull conduit on midship cockpit designs or on boats with a

Guides and Installation Instruction sections for more complete information on specific systemsIFor complete waranty information see inside f r o n t coverThe value of this chart is twofold One to get steerer output secondly to get a working relationship between steerer output and equivalent tiller length To obtain the equivalent tiller length divide the output figure by 40 For example a boat with a 24 wheel and a 12 quadrant has an output of 432 ft Ibs Divided by 40 this equals the leverage of an 11 foot tiller Second it is interesting to note that a 30 wheel with an 8 quadrant has the identical output of a 20 wheel with a 12 quadrant the difference being the number of turns The first with 18 turns has fast action and a large wheel the preference of most racing skippers The second with 27 turns has a sloweraction and a smaller wheel for the boat used primarily for cruising Which do you prefer We can fit the steering action to your boat19PEDESTAL STEERERSAll Edson pedestals are designed for versatile installation in virtually all types and sizes of boats A well designed and well installed pedestal with its greater mechanical advantage gives better boat handling with more feel than a tiller and far more usable cockpit space A pedestal enables the entire family to handle the boat under virtually all conditions Edson offers 4 basic pedestals The Fig 334 is usually used on smaller boats and includes a molded compass adapter for smaller 3 4 or 5 flush mount compasses The Fig 335 is the same basic pedestal as the Fig 334 only it comes without the molded compass adapter and it will accept most all standard 5 compasses The Fig 400s and 420s Deluxe Pedestals for larger boats will accept most all 6 compasses and come equipped with extra needle bearings and liners and the pedestal brake is standard When choosing a pedestal remember all pedestals look somewhat alike on the outside yet the inner workings are most important For instance the 334 pedestal comes with the same 8 roller chain used in our larger pedestals Edson does not believe in compromising by going lighter for a smaller boat as the loads can become high under storm conditions All edestals are predrilled to accept all accessories shown in the catalog with a minimum amount of installation time Please note compasses are not included with the pedestal for compass selection see Fig 658 in this

various quadrants listed below are shown by rudder post or bore size and are available in different models including Space Saving Offset standard straight Double Offset and Dual Ratio Quadrants When ordering please supply an accurate dimension of your rudder post or the desired bore along with the key size and Edson will machine the quadrant to suit Edson allows a 5 to 6 thousandth clamping action of the cap to the rudderpost The quadrant must be carefully fitted for optimum strength if it is fitted too tightly the cap could try to bend when tightened and if fitted too loosely the quadrant could work or drop Both the above could cause premature failure Solid stock rudderposts are normally keyed and hollow pipe stock rudderposts are normally pinned Edson will provide the pin with the predrilled cap Edson sees a trend toward machined keyways in hollow rudderposts as they allow for easy adjustment up and down the rudderpost Most keyways are 114 square so they do not penetrate the wall thicknessu 4 s e Quarpmt t FIG 857 Double offset Quadrant S e g e n t mof the tube Quadrants for square rudderposts require special machining and we must be furnished with the exact

and above the waterline stuffing box Edson offers two types of stuffing boxes starting with type B for the most common used rudder shafts measuring 1 through 3 in diameter Type B Stuffing Boxes are designed to be either fiberglassed in place or fastened to the rudderpost tubing with hose and hose clamps Type C for the less frequently used and larger size rudder shafts through 3112 must be glassed in place Edson recommends fiberglassing the stuffing box bearing to the top of the tubing when the rudderpost is in place This makes the post a structural bearing and will carry the rudder loads with minimal friction The hose coupling method can be used however when under a load the stuffing box is apt to bend and add friction to the steerina svstem When used with hoses the following

their best when they have a strong convenient hand hold Edson guards are available in wide and narrow models The guard is designed to protect the compass from falling crew members and to keep lines clear of the compass The Narrow Guard allows crew members to easily slide past and the Wide Guard is excellent for wide cockpits or where the pedestal is located against a bridge deck It affords extra protection on those boats with a main sheet or traveller just forward of the pedestal Both Narrow and Wide Guards are also available for the bridge deck or seat risers These offer an excellent hand hold when coming up out of the companionway or stepping athwartships Edson guards are also excellent for mounting binocular holders teak cockpit tables winch handle holders and cockpit umbrellas

especially handy on long runs orwhen operating under power Can also be used to hold the boat on course under most conditions while the helmsman trims that sheet or goes below As a safety feature the brake can always be overridden by the helmsman All mounting holes in the steerers are predrilled at the factory allowing simple installation in about 15 minutes Brakes are constructed of bronze with long lasting brake lining and supplied with stainless steel shaft and shiny black brake handle The handle is designed to pop if a line gets tangled an added safety feature When the boat is unattended secure the wheel with the brake In rough weather the rudder can swing violently from stop to stop causing damage Note If you do not own a wheel brake you must tie off your wheel at no time should your

The latest trend of mounting the instruments on the steering pedestal has several distinct advantages It provides for a neat andefficient steering area the helmsman has an unobstructed view of the instruments the instruments become more serviceable and of course it no longer becomes necessary to drill and cut into the boats deck house Edson has now designed housings and pods for one two three or four Pedestal lnstrument Displays All are designed with the Edson Pedestal Guard which not only protects the crew and the instruments but in turn permits the owner to have a table and other pedestal accessories These Guards are positioned 4 forward of the pedestals to allow the top housing or pod to be well forward of the compass lubber line this aives the helmsman a clear view of the compass AII d s o n Housings and Pods are of hand layup fiberglass with a white polyurethane finish The Pods swivel around to be easily viewed by other crew members in the cockpit The Black Plastic

conduit in a midshipcockpit top drawing shows theconduit running down the starboard sideof a37 footer the end fittings of the conduit are attached to the gussetts or reinforcing that is normally located below the aft bunk This type conduit can run through a sail locker or in a hanging locker as the wire is totally encased and there is no chance of the moving wire catching or jamming Being conservative we have limited the PullPull to boats 42 foot or less as we feel that long lengths of conduit would reduce the sensitivity of the steering However small sections of PullPull conduit can be used on any size boat In our continuing program of development these systems have been experimentally installed on several 48 foot motorsailors with excellent results The next drawing shows a very popular method of running the conduit that of straight down the center of the boat and then up to two of the new sheavelconduit idlersand then into thequadrant As can be readily seen there are two lengths of conduit that carry the steering cables from the pedestal down and aft past the engine and they are terminated at a strong bulkhead alongside the propellor shaft There are then free lengths of wire that go aft to an area just forward of the rudderpost and the conduit is again used This aft conduit need normally only be 3 or 4 feetin length and would lead the steering wires up and out to two sheavelconduit idlers and then 90 degrees into the quadrant With two seperate conduits per side the cost is reduced the friction of excessive length is reduced and maintenance is made much easier Also shown is a very popular 36 foot Pilot House Sloop using a combination of sheaves and conduit to give a good The forward steering station uses an Edson Figure 338 Bulkhead Steerer going down to a

sailing craft Basically thesystem is used in conjunction with apedestal or bulkhead steerer and theconduit takes the placeof of the installation makes this method of steering very appealing The PullPull conduit is made with an inner core of polyethylene which is covered by many strands of steel wire These wires are then wrapped with aflat wireand is then sealed by a plastic cover The steel wrapping gives the conduit that extra strength and is exclusively an Edson featureThe conduit comes to Edson from the aircraft industry and has been successfully tested to 600000 cycles without failure The Edson Figure 827 Lubricant which is used in maintaining the PullPull system is an inert base oil combined with Teflon and is an important addition as it reduces friction bv about 30 oercentThe easiest of all methods is that shown here that of takina a bulkhead steerer on either power or sailboat and run it out aroundThe conduit can snakearound neatly through a cabin area or over and around a tank heaterexhaust line In effect we recommend PullPull where straight line sheave to sheave wheel cable systems are difficult to fit We find that on many pilot house boats with dual steering stations that the aft steerer will be all sheaves but the forward station will use a combination of sheaves and PullPull conduit The conduit will be used fora length of 8 to 10 feet as it snakes down the interiorwhile going upand over and down an obstacle and then into a Radial Drive or other sheave SAILBOAT the following pages we are showing the various methods of installing the conduits as well as the different specialized hardware designed by Edson to make the installation easierand also to allow for easier maintenance and inspection of the completed system As in all steering systems the basic setup should be made to use as many of the existing structural members as is reasonably possible If a bulkheadcan belocated to serve as an anchoring point for the conduit or one of the new conduit sheave assemblies so much theeasier Needless tosay the bulkheads must bestrong and up to the steering loads that will be put upon them The aft plywood gussetts mustbe adequately reinforced to accept theend fittings of the conduit An easy way to locate theend fitting is by placing a inch dowel or rod in the groove of the quadrant and at 90 degrees to the centerline go to the gussett which is fore and aft and drill a la inch hole for the conduit end fitting see illustration With the dowel in the other groove of the quadrant drill the opposite gussett for the opposing

STEERING SYSTEMSWhen planning your steering system it is best to think ahead AutoPilots are more popular than ever and easier to install Edson nas developed three basic methods of attaching autopilots first all Edson Bulkhead Steerers Rack and Pinion and Worm Steerers can have autopilots attached directly to the wheel shaft extension or the wheel shaft itself nothing extra to purchase Second the use of the Edson Figure 320 AutoPilot Drive with the addition of one or two sheaves and the appropriate roller chain can adapt virtually all Edson Pedestal Systems to AutoPilot attachment With the 320 the boat can use an extra quadrant or radial drive for a completely separate system or can introduce the 320 in to the basic wire system Third the all new Edson Rapid Drive for a right angle gear box drive the simplest system for owner yard and boat builder As a general guide the simpler the system the better On any installation involving electricity the area must be well proteted from moisture and the wires used must be of the correct size and used with good solid terminal ends At no time can the unit be exposed to salt water such as would occur if the electrical panel was placed below a sail locker As obvious as this may sound we still see many units so mounted The compass unit must be kept away from the boats navigation compass as well as from other interferences such as an alternator on an engine Take the Fig 320 Pedestal System first There are two basic concepts that can be used in the installation of an automatic oilot with a oedestal One is to place the Fig 320utopilot Drive Unit withinthe boats existing steering system This would be as in illustrations 1 and 2 A second method would be to use a second auadrant or radial drive that would in effect make an independent system here is a great deal of merit to this latter approach as any boat would then have three methods of steering There would be the egular boats steering system the automatic pilot driven by electricity and the emergency tiller The extra quadrant or radial drive would eliminate having to cut into the boats system and is generally the preferred method for conversion to an autopilot As can be seen in Figs 3 and 4 the extra quadrant or radial drive can be placed above or below the regular steering systems quadrant or radial drive and in the case of the quadrant on either the forward or aft side or for that matter on a fore and aft plane The ultimate choice is determined by where you have room for the actual pilot TYPICAL AUTO PILOT ARRANGEMENTS NOTE See Midship

in your steering system so they can recommend the proper size drive sprocket The number of turns and length of roller chain for a given size quadrant or Radial Drive is shown in the selection chart for each type steerer In the case of conversion to a pilot h i t h a pedestal it is necessary to purchase the following items 1 Fig 320Size 2 Auto Pilot Drive Unit 2 an appropriate length of 5 Roller Chain Fig 630s The length is determined by the quadrant or Radial Drive size to which the pilot is to be attached This should be accompanied by the necessary wire rope roller chain master links end fittings and the necessary extra sheave or sheaves to accomplish the installation Be sure to use the same size sheaves as are in the regular steering system for the boatThe Rapid Drive and the AutoPilot must be securely held to a platform The electrical wirGg to the AutoPilot must be of the size recommended by the AutoPilot maker and fastened with good solid terminals The installation must be protected from moisture As in all exposed gearing the Rapid must be covered by a clear Lexan or equivalent cover to keep equipment and fingers out of the mechanism The clear cover permits ready visual inspection Maintenance of the Rapid is simple use 30 or equal Motor oil on the shaft bearings and on the geared segments and wipe across the bottom of the segment Water pump grease can also be smeared on at this point The unit should be inspected like all steering equipment and it is wise to checkand oil it at least once a AND INSTALLATION GUIDEAFT COCKPIT STEERINGpI iENGlNEERlMG AND INSTALWTBON This Aft Cockpit planning guide has been written to assist the boat owner boatyard and the designer in making the most convenient pedestal installation for any given cockpit design Before making a final decision on the location of the steerer it is always a good idea to make a dummy steerer out of a 2 x 4 a short length of broomstick handle for the shaft and a cardboard or plywood cutout of the chosen wheel size At the same time the area below the cockpit floor should be checked for obstructions such as tanks lines etc and also to check to see if the builder installed cockpit floor reinforcing and its exact location The location of the winches and the helmsmans visibility should also be notedAFT COCKPIT STEERING 6 shows the rudder post forward and the steerer aft Note that the wires can run forward or aft to the quadrant If the steerer is placed up against the rudder post the forward side of the base can be Milled off to gain space With the helmsman aft all of the crew is forward and they must handle the sailing of the boat as the helmsman can not contribute any reasonable assistance This is usually no problem on a 45 footer that requires a larger crew but on a 35 footer or less i t can present problems However when cruising this can be an advantage since the skipper can supervise sail handling and keep track of children and 2 shows a forward steerer installation using Edsons quadrant and sheaves Note how the Clutch and Throttle Control is safely nested between the wheel and guard This prevents snagging lines or accidental shifting while keeping controls close at hand the helmsman does not have to look away during that important manueverlllus tra tion 4lllustration 4 shows pedestal in mid cockpit using PullPull shown in a particularly complicated arrangement This illustration shows the PullPull conduit being run between quarter berths and around a tank where wire rope and sheaves would be very difficult to installTYPICAL OUTBOARD RUDDER 1 Forward 1 shows a steerer forward using Radial Drive By plating the steererat the forward end of the cockpit the helmsman has the protection of the companionway dodger and has quick and easy access to the cabin below The forward location also keeps the cockpit activity aft of the helm and when in shorthanded situations allows the helmsman to steer and handle the sheets with the minimum of difficulty Edson suggests using a large size wheel within 2 or 3 of the cockpit seats if the boat has a bridge deck as there will be no need for guests or crew to slide by the wheel We also recommend the installation of a pedestal guard as a handhold for crew members going below The larger wheel will allow the helmsman to comfortably lean against the coaming and to have excellent allaround visibility In many conversions from tiller to wheel the forward locations makes for the least cockpit layout change as i t places the helmsman in approximately the same location with the wheel as with the tiller For a racing boat all the action is aft and when not tacking the crew can sit to weather and forward if it improves the balance of the boatPullPull easily adapts for use with outboard rudder boats As shown above cables run beneath the sail locker on one side and under a quarterberth on the other lllustration 3 shows a pedestal steering installation on an average 25 to 30 footer with transom hung rudder The Edson Fig 612 1 I Quadrant series can be used on most all boats of this design The quadrant should be mounted fairly high on the rudder to fit within the lazarette or so a box or helmsmans seat can be built over it as illustrated As a rough guide to the following Fig 612 Quadrant sizes should be used Boat Length 20 to 36 feeff611 m I 0 inch size126 cm 37 to 45 feeff1214m 14 inch size136 cm 45 to 60 feeU1418 m 20 inch size150 cm The above chart must be used with caution obviously a very hardtosteer boat must go to the next size larger quadrant than is indicated With all Edson Pedestals the quadrant size in inches is roughly equal to tiller length in feet As in any opening in the transom it must be booted or a drain pan or area must be installed to prevent water from getting into the structure of the boat As a further guide the 10 quadrant requires a transom hole of about 25 cm by 615 cmlllustration 7In lllustration 7 the rudder post is vertical and there is a quarter berth on the port side aft The solution was to mount the quadrant angled to one side and to lead one of the wires directly into the quadrant and the other aft to a sheave and back into the quadrant As a matter of interest one of the earlier boats on which this was done was a 36 footer The idler sheaves were 410 cm as the wire only went around the idler sheaves 90 degrees On the aft single sheave i t was 615cm as the wire goes around it about 180 degrees the larger sheave will increase the feel of the rudder from reduced wire friction GENERAL As in all installations Edson tries to reduce the number of sheaves They must be bought installed and each one adds its friction effect A good needle bearing pedestal with as few sheaves as possible with well oiled bushings and a well hung rudder will give a very sensitive system and one that is free of problems The T Cockpit can have the steerer placed aft pictured so the helmsman is sitting on the aft seat and sliding around to the sides or another variation would place the pedestal well forward in the cockpit and bring the primary winches aft by the base of the T so the winch grinders can stand by the handles Likewise downwind under a spinnaker i t would give the sheet handlers more room and hopefully less chance of error One distinct advantage of the aft steerer arrangement is that the helmsman can see all that is going on in the cockpit an important factor when racing When the steerer is placed at the extreme aft end of the boat be sure that the jib luff can be easily seen and i t not being visually blocked by the maini The aft location of the wheel in a long narrow cockpit is the traditional location of a pedestal The helmsman can see all of the action and if a line jams or some other problem develos he can take the best corrective action if the steerer is well aft itis a good idea to put on the narrow pedestalguard and for the engine controls to be placed on the steerer When planning this installation beware of such potential problems as a tall helmsmans head hitting the backstay or the possibility of the main sheet catching the pedestal also be certain you have enough space at least 16141 cm clearance behind the wheel to allow foot room at the helm At Edson we can always tell when a pedestal is too far aft there are heel marks on the end of the cockpit where the helmsman has tried to move his feet aft and found no space lllustration 5 shows a cockpit with the steerer aft and in this case a separated helm Note that all of the steering mechanisms are within the cockpit bridge The quadrant is mounted on the aft side of the rudder post which necessitates crossing the cables within the pedestal Note the Fig 727Safety Clutch can bring the control cables down just aft of the bridge deck so they lead directly to the engine and do not get involved with the bridge deck and the moving POSITION Placing the steerer in the middle of the cockpit or within two feet of either end can give a good balance The crew can be forward or aft whichever makes the boat go best With the steerer in the relative center of the cockpit the spinnaker winches can be aft and the genoa winches forward when racing this keeps the spinnaker action behind the helmsman and yet allows the helmsman to assist with the jib winches if needed When cruising the midcockpit arrangement enables the guests to relax aft and not get involved in sailing the boat while the skipper can steer and tack the boat with easeIP When placing the pedestal at midcockpit keep at least 1538 cn clearance from the bridge deck or companionway This will p r e w vent a crew member from having to stand with one foot on the bridge deck a situation The helmsman normally will sit to one side of the wheel or stand behind the wheel Edsons Helmsmans Seat can fit neatly between the seat risers and its arched center section raises the helmsman for better visabilityi 3lllus tra tion 6Please remember

COCKPIT AND IMSTALWTION This guide has been prepared to enable the designer builder and boat owner in planning out the various methods of installing a wire steering system in a midship cockpit boat Edson offers two types of wire rope systems for the midship cockpit boat the conventional wire system and the new PullPull Conduit Steering System ideal for boats up to 42 in length Regardless of the type and size of midship cockpit boat the steering system should be thought out at the time the boat is designed or at least before the interior is in place There are virtually no boats that can not be adapted to a wire system Whichever system used the advantages of a wire system are many and important The system is simple this makes it excellent for those boats going offshore or to remote areas A roller chain pulls the rudder to one side or the other If the wire fails you can rig a new wire Try that with other types of steerers It is in effect a screw nut and bolt philosophy of design The steering will give the boat a personality There is feel response flexibility and if you want to settle down put on a dampening brake add a simple mechanical AutoPilot These will give you the best of all worlds PLANNING FOR THE WIRE ROPE SYSTEM When using wire rope and sheaves we are dealing with a series of straight lines or for the sake of visualization straight connecting rods lllustration 1 shows two basic methods we will call them port and starboard for the sake of simplicity Starboard The wire is led to starboard just under the deck level over the heads of those passing through the aft cabin passage The wire is then led aft just inside of the sheer line to a turning sheave which directs the wire intoPort The steering cable goes engine trunk anddown to a sheav engine room floor level then aft to a sheave and up to a sheave aNeedless to say both Port and Starboard can be run the same down or to the side it is all a matter of taking the best course for the available space and the location of suitable attaching structures for the sheaves The AutoPilot has been attached to a second quadrant mounted on the aft side of the rudder post and in this case down low With the separate quadrant the boat has in effect two steering systems one automatic one mechanical For further AutoPilot information see AutoPilot section lllustrations 2 and 3 show the most commonly used method of runnina the wire in a midship Cockpit Boat The wire is run to either the port or starboard side by using the Edson Fig 607 Adjustable Idler This directs the wire aft a small amount down a small amount to double sheaves that are mounted on the aft engine room bulkhead Care must be taken to make sure that the wire is clear of the aoorooriate sail lockers The wire is then directed aft at a level just under the bunk top and on the outside of the backs of the drawers in an area aenerallv considered to be otherwise unusable In manvcases the wire is run alona the exhaust line trunk Aft the two sheaves are mounted on a stiffening bulkhead one sheave leads the wire directly to the quadrant the other sheave across the boat to a sheave and then back to the auadrant Care must be taken to make sure that the wires are led correctly to give the boat directional rather than reverse steering This installation points to the importance of using existing or planned bulkheads and stifi6 fening for mounting of the sheaves easier stronger a n a i h simpler 4 11 lllustration 2 the AutoPilot steering cables have been diverted so the pilot can be mounted on a shelf in the aft end of the engine room in an otherwise unused but generally crowded area0MlDSHlP COCKPIT STEERING 3 shows another form of placing the Pedestal in the MidShip Cockpit Boat The wire is basically led down and run beneath the aft cabin sole The Pedestal can be placed aft in the cockpit with the possibility of placing the helmsman on a raised seat for better visibility over the 3Illustration 2This installation assumes the engine is directly below the Pedestal and it is necessary to place Fig 607 Adjustable Idler under the pedestal to direct the wire aft a small amount The sheaves at the floor level can be placed on the very aft end of the engine compartment and they in turn will lead aft to two sheaves placed on a transverse bulkhead directly under the aft cabin floor These in turn direct the wire aft up and out to two sheaves mounted on the O u n k front bulkheads and then directed into the quadrant Emergency steering can be placed on top of the rudder post by simply removing the aft cushion and by placing a tiller at this point Some owners prefer an extension that goes through the aft deck to allow placing the tiller over the aft deck house This is a personal preference but by all means have an emergency method of steering The lllustration 4 installation is used on boats with passage ways toilets or lockers on both sides of the cockpit foot well With this layout one way to steerthe boat is to run the wires under the floor of the aft The wire is then directed aft under the floor in the natural V of the hull Aft to two sheaves which can be placed on a simple structure and then out and up to two sheaves and then into the quadrant Note how the sheaves can be fastened to existing bunk fronts andlor bulkheads Very important to keep costs in line as well as to keep the structures simple PLANNING FOR THE PULLPULL SYSTEM Edsons new PullPull Steering System is ideal for midship cockpit boats up to about 42 in length The PullPull System is an alternative to the standard wire rope and sheave installation The following illustrations show just a few of the many uses of PullPull Steering lllustration 5 shows a Destroyer Wheel with a Fig 338 or 410 Steerer mounted in a cockpit moldment The moldment houses engine and controls while serving as a table for cockpit entertaining Since the quadrant is mounted on the aft side of the rudderpost the cables are crossed within this structure for proper steering direction In this case one cable runs along the port side to the quadrant while the other cable runs directly down the starboard side With this type installation the cables can be anchored to an existing moldment or plywood reinforcement Here it is attached to the plywood reinforcement normally placed under aft bunks lllustration 6 shows the Pedestal installation using the 841 Mounting Plate for attaching the cable The cable is routed along the starboard side under a bunk to a Radial Drive One wire can run across to a sheave mounted on the other side and back into a regular quadrant if space PULLPULL CABLE AND SHEAVES lllustration 7 shows the cable running down over the engine and aft under the cabin sole With the sharp bends aft the system converts to a standard wire rope and sheave arrangement connected to a quadrant or Radial Drivefor further in formation please refer to the and the How to f the tion 1The Pedestal can be placed at the point up against the ridge deck or in the normal aft position in the cockpit If laced forward it does allow the helmsman to be protected Q n poor weather by the dodger In addition the engine controls and can all be mounted on the aft end of the house This can then place all of the wiring in an easily accessible trunk within the main cabin The wire from the pedestal goes down and is Veed slightly to allow the wires to go to sheaves fastened to the STEERER INSTALLATION This section has been prepared for both amateurs and professionals to assist in the installation of the Edson pedestal steering systems We have tried to take the installation step by step in hopes the job will not only go faster but also much easier You will find many suggestions along with simple illustrations to guide you but in the marine trade

CONTFor hollow pipe stock the Drive Wheel or quadrant must be positioned on the post by tightening the bolts Only after all the final measurements and adjustments for the entire system have been the hub and rudder post for a stainless steel pin The third system is an alternative to cutting a keyway in solid stock or through drilling for a pin in hollow pipestock The same positioning method as used for the pin must be observed and only after all final adjustments for the entire system have been made drill and tap for two stainless steel Ysn1952mmcap screws through the hub and well into the rudder pThe actual drilling operation whether for the pin or for the set screws should be the last step in the entire mm 11615mm HOLEmust be installed if the cut is less than 12 to 15 above the waterline and the boat should be hauled for this operation Where the cut will be made is determined by the location of the Radial Drive Wheel or auadrant and the size of the idler sheaves see Figs 1

FIG 9f l 7LOCATION OF PEDESTAL STEERER After carefully unpacking the Edson equipment lay out all the components and familiarize yourself with the system by arranging the parts as closely as possible to the order of assembly From the architects drawing or the boats data sheet find the ideal location for the installation of the pedestal steerer Set your pedestal with the wheel attached at this position and check the cockpit layout Will you be able to crank your winches Sit and stand comfortably Will the main sheet clear the wheel Adjust your steerer until you are satisfied you have the best location possible We suggest at least 21 154cm from the pedestal base dead center aft to the rear of the cockpit for standing room Now check the area under the cockpit floor to make certain the pedestal location chosen will allow freedom of installation for all the components With the pedestal carefully aligned fore and aft and centered use Edsons Template EB237 furnished with each order to mark the location of the four bolt holes At the center drill a thru hole 675mmdia This tiny hole will mark the pedestal location when working under the cockpit floor Do not drill any other holes at this time The small hole can easily be filled should you decide to relocate the steerer PREPARATION OFTHE RUDDER POST I f you are ordering a new boat with a tiller but plan to add a pedestal steerer at a future date have your boat builder install a stuffing box and key the rudder post This can be done by the builder at a nominal cost and will make the steerer installation far easier for you when the time comes If your boats rudder i s equipped with a stuffing box the Edson may be installed with the boat in the water If your rudder post enters through a fiberglass tube from the hull to the floor a portion of this tube will have to be cut away to expose the rudder post for the installation of the Radial Drive Wheel or the quadrant Although Edson recommends a stuffing box some boats with high enough freeboard can do without one A stuffing boxlm I I151127cmfor 4 sheaves A suitable stuffing box should be used to seal the rudder post at the tubing Edsons Fig 697 Stuffing BoxlBearing is preferred as it serves as additional bearing however hose type stuffing boxes may be used Edson stuffing boxes are available for rudder posts from l1251cm diameter 3189m diameter and are approximately 41702cm in length The stuffing box must be installed above the water line It mounts on top of the lower cut in the fiberglass tube see Figs 1and 2 and is heavily wrapped with fiberglass and epoxy resin As on all rudders be sure and place the Fig 697 Stuffing Box within about 11zl38cm of the bottom of the quaddrant or Drive Wheel and supbort it well for the rudder loads Figs 1 2 6 7 and 8 show typical stuffing box arrangements With the rudder post back in the boat place the drive wheel or the quadrant onto the post at the determined position NOTE As a simple safety factor install a stainless steel hose clamp directly under the quadrant or Drive Wheel This will prevent slippage if the quadrant or Drive Wheel were to loosen in service PEDESTAL SUPPORT3 RUOOERRADIAL DRIVEFIG 10C O

lowering the Drive Wheel on the rudderpost Be sure and cut the keyway longer than necessary for final adjustment When locating the keyway decide whether you will be mounting the Drive Wheel hub up or hub down because the wire line is not at the center of the hub Cable tension is adjusted using 2 Fig 618 Wire Rope Takeup Eyes as in the standard quadrant system On pedestal installations with the rudderpost raked forward or aft you may require a block of wood between the cockpit floor and the idler to lower the idler for a good lead to the Drive Wheel An alternative sometimes used on racing yachts for ultimate feel is using a 6 idler to lower the wire lead The Drive Wheel is supplied with a welded steel rudder stop which can be mounted above or below the Drive Wheel forward or aft See Figs 27 thru 32 for installing proper stopsFIG 2 There are three methods of preparing and attaching the Radial Drive wheel or the quadrant to the rudder post The most secure method for solid stock is cutting or milling a keyway in the rudder post and the drive wheel or quadrant Be sure and cut the keyway longer than necessary for final adjustment and the possible addition of an autopilotOn many boats the cockpit floor will require beefing up at the pedestal one method is to install a piece of 12113mm to 3hr 19mm plywood about 2 feet square under the cockpit floor see Fig 9 COCKPIT FLOOR l 111615mm HOLEGLASS PLACE INWOOD SUPPORTFIG 9li 1PFIG 4PIPE STOCK wood should be securely fastened by glassing in with epoxy resin and several layers of mat fiberglass kits are available from your local marine dealers The strain of a pedestal steerer on the cockpit is severe and we recommend this type of suppart The wood support also makes a smooth working surface for mounting the idler sheaves

Up t o 4 i f specified in y o u r STEERER INSTALLATION CONTMETHODS FOR INSTALLING SHEAVES 1 The sheaves may be mounted on wood supports that tie the cockpit to the bottom of the boat and keep the steering loads from wracking the cockpit with resultant bending of the rudder post 2 The use of an Edson Fig 739 or 740 bracket that bolts to well glassed in wood blocks This system is excellent for those boats that have an adequate transverse bulkhead to take the loads INSTALLING SHEAVE SUPPORTS Fig 12 shows the time honored Edson Method of glassing in wooden sheave supports The port side shows the wood support running from the inside sail locker to the bottom of the boat It should be glassed or bolted and made smooth so it does not catch your sails The starboard side indicates a modification when a quarter berth or other structure limits the use of the cockpit bulkhead Here the sheave support butts against the cockpit floor or pedestal support Use straight grained mahogany approximately 1Mx 8 and long enough to reach between the outboard side of the cockpit seat risers and the hull Bond in place with epoxy resin and glass cloth for added support we recommend a wood same stock spreader between the two sheave supports see Fig 12 INSTALLING BRACKET The Figs 739 and 740 are alternative methods that can be easier on those boats where the cockpit seat risers are alongside the radius of the quadrant and the pedestal is as shown on Fig 17 This system can be used with the Edson Method or mounting wood blocks for the necessary sheave support The preferred sheave bracket installation shown in Fig 17 uses approximately 21 5crn by 12130cm to 18146crn wood blocks glassed into the sail locker sides of the cockpit floor When necessary to bolt thru the cockpit floor keep as wide as possible with the bolts as near the edge of the cockpit gutter as possible This reduces the chances of oil canning the floor and resulting cracking of the gel coatJuLLPULL INSTALLATION When installing the PullPull System the two conduits can either be routed port and starboard Fig 19 or both down the same side Fig 20 If space is at a premium lead both conduits down the same side and then route one wire across to a sheave mounted on the opposite side and back to the quadrant Fig 21 The conduits must be terminated by drilling a 3hr1 hole in either an existing moldment or a plywood bulkhead Anchor the conduits in place by using the nuts and washers supplied Fig 22 When terminating the conduits make sure they lead the wire rope properly either to the steerer or to the correct groove of the Quadrant or Radial Drive The PullPull conduit has a minimum bending radius of 8 and for the smoothest steering try to keep the number of sharp bends to a minimum Once the system is hooked up tighten the wire rope to eliminate all play but do not overtightenr 3PEDESTAL STEERER INSTALLATION CONTUse 3hs1476mrn for 4llOcm sheaves or 1 h 1635mm dia for 6 sheaves Secure the roller chain adapters to one end of each length of wire use nonmagnetic fittings do not use wire clamps as they might lock within the pedestal Be sure the chain is centered over the sprocket when the quadrant is centered midship rudder in fore and aft position This is important to keep end fittings on the chain from overriding and damaging the sprocket Lead the two wires around the idler sheaves the outboard sheaves and around the quadrant to the eye bolts The eye bolts should be in a slackoff positionFig 24CLEVIS HEADFIG 618 TAKEUPTWO WIRE ROPE CLAMPSFIG 16When installing the Radial Drive lead the wire rope directly from the idler around the Drive Wheel to the eye bolts Fig 25 Secure the wire rope with the wire rope clamps see Fig 24 and 25 Tighten up the cables with the eye bolts but do not overtighten To properly tighten cables lock the wheel in position using the pedestal brake or by tying off the wheel Cable tension is best when you cannot move the quadrant or Drive Wheel by hand with the wheel locked in place Overtightening will greatly reduce the sensitivity of the system With one person at the wheel and one watching the machinery turn the wheel from hard over to hard over checking for any binding or misalignment in the system The man at the wheel can check to see that the ends at the chain never reach the sprocket8 FIG 12FIG 13NOTE For RADIAL DRIVE cross the cables inside the pedestal for proper steering SHEAVES The location of the sheaves is crucial for any misalignment will cause binding in the system The edge of the sheave which receives the wire from the quadrant must be on tlie same plane as the correct groove i n the quadrant see Fig 15 Simply adjust the outboard sheaves using the c clamp up or down until the two sheaves and the quadrant appear to be on the same level see Fig 15 This can be done visually but as a check you can use a level or take measurements from the overhead FIG 17FIGPEDESTAL INSTALLATION Install the pedestal as shown in Fig 23 using four Fig 646 Pedestal Mounting Bolts ALIGNMENT OFTHE SHEAVES Alignment is not difficult but must be done with care One of the easiest methods is to substitute shock cord for the wire

wire needed and cut off two lengths of stainless steel wire 7 x 19 nonmagnetic about two feet longer than the required lengthPEDESTAL STEERER INSTALLATION CONTINSTALLING THE RUDDER STOPS The steering system must have stops to pick up the loads at the hard over position Although Radial Drive Wheels and Sheave Brackets are supplied with rudder stops the preferred method is to install the rudder stops into the hull independently of the steering system Rudder stops must be installed to prevent the rudder from hitting the hull or the chain adapters from damaging the sprocket Be sure the stops are strong for they will take a lot of strain at one time or another during the life of your boat The following sketches show the best methods of installing the stopsCONDENSED EDSON PEDESTAL MAINTENANCE GUIDEf All Radial Drive Wheels are provided with a rudder stop The stops can be mounted fore or aft and to either the top or the bottom of the drive wheel Figs 27 and 30 Blocks of wood should be fiberglassed in place for the stop to hit Stops must hit squarely and as low on the stop as possible The best rudder stop arrangement Fig 37 uses a tiller arm or its equivalent as a stop This keeps the stops independent of the steering An alternative method for the rudder stop is to place a straight grained mahogany beam athwartships and cut out two notches for the stop to hit squarely keeping the total travel of the Drive Wheel between 60 and 70 degrees Fig 3 2 8LAZARETTE FLOOR LIUDDER STOP2 x 4 POST CAN BE SECURED TOP AND BOTTOM UNDER COCKPIT OR BOLTED TO BULKHEAD OR

both solid and hollow stock rudder posts Before modifying your rudder post be sure the tiller head fitting is not the thrust bearing holding the rudder up in the boatiThis guide has been prepared to assist you in the proper maintenance of your Edson Steering System To properly maintain the moving parts in the top of the pedestal it is necessary to remove the compass and its cylinder For proper alignment when reinstalling the compass we recommend placing 3 or 4 lengths of tape on the pedestal and compass as shown below Slit the tape when removing compass align the strips of tape when reinstalling the compass for visual compass realignment Your compass MUST then be checked for accuracy Lubrication of needle bearings should be done by squeezing Edson Fig 827 Teflon Lubricant into the holes located on top of the bearing housings inside the pedestal bowl Spin the wheel when squeezing the lubricant in to make sure the entire bearing is serviced Winch grease or water pump grease can be used as an alternative but dont let the bearings run dry Do not over grease as it will run onto the brake pads Oil the chain with 30 weight motor oil Do not grease chain as it does not penetrate the links Inspect the condition of the wire tension of the wire and lightly oil Edson recommends placing about 5 layers of Kleenex on the palm of your hand squirt oil on the tissues and lightly oil the wire This will lubricate the strands but will also flag a broken or hooked strand by tearing off a small section of tissue fyou do have a wire break replace the wire immediately See Edson Fig 775 wire and chain repacement kits Calltion Wire splinters can cause painful cuts Replace the wire after5 vears If still aood keeo the old wire on board as a soare o check for proper wire tension lock thewheel in by using the pedestal brake or by tying off the wheel Cable tension is best when you cannot move the quadrant or drive wheel by hand with the wheel locked in place Over tightening will greatly reduce the sensitivity of the system O l t must be emphasized that all on board must be familiar with the care and operation of the Steering System and engine controls One person must be assigned the job of maintenance and must be thorouahlv familiar with the oeration and intent of all the equipmentlf at any time you Steering System makes strange noises or reacts differently than it has previously you must find the causes immediately and correct the problem Screws nuts bolts as Well as clevis and cotter pins that are part of the steering system engine controls or pedestal accessories must be checked regularly fortightness and wear Failure to insoect all steerina oarts enaine controls and edestal accessories may cause loss of control or failure of the engine or steering system All boats must have an emergency tiller or its equivalent and all on board must be familiar with its location and operation An emergency tiller drill is just as important as a manoverboard drill and must be regularly conducted On a new boat and at least once a year inspect the system when under a strong load On a calm day and under power go away from the other boats and with the person who is assigned the maintenance watching from below put the wheel hard over at full throttle The maintenance man should watch carefully for all parts of the system bending distorting creaking or giving any indication of failing if placed under a heavy load for a period of time If for any reason something did fail or needs adjusting the day is early and you will have plenty of time When leaving your boat at her mooring or slip make sure that your Edson wheel brake is tight or that your wheel is properly tied off DO NOT LEAVE THE STEERING SYSTEM TO FREE WHEEL The pedestal

owner wants a sinking boat let alone have a little water over the floor boards If such a situation does arise the boat owner should always be well prepared for any type of emergency with a large capacity Bilge Pump For handling large volumes of water the Diaphragm Pump is pump on the market If you currently have an electric bilge pump use it for that daily job however we strongly recommend that you have in addition a hand operated Diaphragm Pump Your pump should always be functional no matter what the conditions of weather or what shape the boat is in Unlike many hand pumps of the old Navy piston type design the Diaphragm Pump will move an exceedingly large volume of water in a short amount of time without exhausting you or your entire crew The Diaphragm Pump is also virtually clog proof Most anything that will pass through the hose can be pumped The larger the pump the more debris i t can handle There are many different Diaphragm Pumps on the market most ranging within the
